Answer:

the answer is -5.3 hopes this helps

Step-by-step explanation:

6a+5b=?

6(4.2)+5(-1.9)=?

6(4.2)= 25.2

5(-1.9)= -9.5

4.2 - 9.5= -5.3

The value of the expression (6a + 5b) when a = 4.2 and b = -1.9 will be 15.7.

When the relevant components and basic processes of a numerical method are given values, the expression's result is the result of the computation it depicts.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given as,

⇒ 6a + 5b

The value of the expression at a= 4.2 and b = - 1.9 is calculated as,

⇒ 6 x 4.2 + 5 x (-1.9)

⇒ 15.7

The value of the expression (6a + 5b) when a = 4.2 and b = -1.9 will be 15.7.

Answer:

  6 m

Step-by-step explanation:

The missing dimension can be found using the volume formula with the known values filled in. This gives an equation that can be solved for z.

The volume of a cylinder is given by the formula ...

  V = πr²h

__

Using the given values, we have ...

  1696.5 m³ = 3.14(z²)(15 m)

  z² = (1696.5 m³)/(47.1 m) ≈ 36.0191 m² . . . . divide by 47.1 m

Taking the square root, we find z to be ...

  z ≈ √(36.0191 m²) ≈ 6.00 m

The value of z is about 6 m.

The exponential form when [x²y³)^(¹/₃)]/[∛x²y] is  simplified gives us; [x^(²/₃) * y]/[x^(²/₃) * y^(¹/₃)]

The power of a digit defines a base number raised to the exponent, where base number is the factor which is multiplied by itself while exponent denotes the number of times the same base number is multiplied.

We want to simplify the exponents; [x²y³)^(¹/₃)]/[∛x²y]

Using rule of exponents, we have;

[x^(²/₃) * y]/[x^(²/₃) * y^(¹/₃)]

Answer: 16 centimeters

Step-by-step explanation:

    We will use the Pythagorean theorem to solve. The c variable is the hypotenuse, the a and b variables are the legs.

a² + b² = c²

12² + b² = 20²

144 + b² = 400

b² = 256

b = [tex]\sqrt{256}[/tex]

b = 16

          The length of the other leg is 16 centimeters.

Answer:

The other leg is 16 cm long.

Explanation:

Use the Pythagorean theorem:

[tex]c^2=a^2+b^2[/tex],

where:

[tex]c[/tex] is the hypotenuse, and [tex]a[/tex] and [tex]b[/tex] are the other two sides (legs).

Let [tex]a=12[/tex] [tex]cm[/tex]

Rearrange the equation to isolate [tex]b^2[/tex]. Plug in the values for [tex]a[/tex] and [tex]c[/tex], and solve.

[tex]b^2=c^2-a^2[/tex]

[tex]b2=(20 cm)^2-(12 cm)^2[/tex]

Simplify.

[tex]b^2=400 cm^2-144cm^2[/tex]

[tex]b^2=256 cm^2[/tex]

Take the square root of both sides.

[tex]b=\sqrt{256cm^2}[/tex]

Simplify.

[tex]b=16[/tex] [tex]cm[/tex]

I am sure you discussed and learned this in class, otherwise you would not get such a problem to solve.

it is a really simple thing : just multiply the 2 numbers.

the area of the shop is

10 × 6 = 60 m²

the really important thing is not to forget that the result is not measured in meters, as this is no longer just a 1- dimensional length. since we multiplied two meter lengths, it is measured in square meters, which are squares of 1 meter side length, and we say how many such squares fit into the area.

Based on the properties of a kite, the statement that is true is: D. KPE = TPE.

A kite is a quadrilateral in which its diagonals intersect at right angles.

Also, the non-vertex angles of a kite are congruent, that is they have equal measure.

Angle KPE and angle TPE in the given kite are right angles formed at the point of intersection of the two diagonals of the kite. They both equal 90 degrees.

Answer:

1. P(2 or 4) - 2/3

2. P(multiple of 2) - 1

3. P(multiple of 3) - 1/3

4. P(odd prime numbers) - 0

Step-by-step explanation:

Good luck lol

P(2 or 4) =  2/3

P( multiple of 2) = 1

P( multiple of 3) = 1/3

P(odd prime numbers) = 0

Probability is the likelihood of an event happening or not.

Analysis:

possible outcome = (2,2,4,4,6,6) = 6

P(2 or 4)

n( 2) = required outcome = (2,2) = 2

P(2) = 2/6 = 1/3

n(4) = (4,4) = 2

P(4) = 2/6 = 1/3

P(2 or 4) = 1/3 + 1/3 = 2/3

n( multiple of 2) = (2,2,4,4,6,6) = 6

P( multiple of 2) = 6/6 = 1

n(multiple of 3) = (6,6) = 2

P(multiple of 3) = 2/6 = 1/3

P(odd prime numbers) = 0

The third term, fourth term and tenth term are -1, -3, -15 respectively.

A sequence is a pattern of numbers in which successive terms differ by an constant term called the common difference or ratio.

Analysis:

For a sequence defined by the rule A(n) = 3 + (n-1)(-2)

Third term, n = 3

A(3) = 3 + (3-1)(-2) = -1

Fourth term, n = 4

A(4) = 3 + (4-1)(-2) = -3

Tenth term, n = 10

A(10) = 3 + (10-1)(-2) = -15

In conclusion, the third, fourth, tenth terms are -1, -3 and -15 respectively.

The two triangles are similar as the angle of incidence is equal to the angle of reflection because the light ray selects the shortest path to reach the destination.

The angle of reflection is the angle between a reflected ray and the normal drawn at the point of incidence to a reflecting surface.

When light is reflected from a surface, then the angle of incidence is always equal to the angle of reflection, where the angles are measured from the path of the light to the normal to the surface at the point at which light strikes the surface. Therefore, the angle of incidence is congruent to the angle of reflection.

Hey there!

Arithmetic sequences are made up of terms that are added or subtracted, and geometric sequences are made up of terms that are multiplied or divided.

Given this info, we can see that we go from 10 to -5. Because we know that this is geometric, we see that we must divide by -2 in our sequence.

We can see that this is true because -5/-2=5/2.

Now, we could simply continue dividing by negative two to get our answer, which is -5/16.

You could easily do that with a calculator, but if you had to find a term that was farther from the first term, that would take forever to do with a calculator, so there is an equation that you can use and plug in your numbers to find the answer quickly.

Answer:

C. 91.46

Step-by-step explanation:

Use BODMAS!

Answer:

C. 91.46

Step-by-step explanation:

Using Pemdas to solve:

5.9 (9 - 5) + 4^3 + 3.86

First you have to solve in the parenthesis

5.9 (9 - 5) + 4^3 + 3.86

= 4

New equation:

5.9 x 4 + 4^3 + 3.86

Now solve the exponent:

5.9 x 4 + 4^3 + 3.86

= 64

New equation:

5.9 x 4 + 64 + 3.86

Now we have to do multiplication:

5.9 x 4 + 64 + 3.86

= 23.6

New equation:

23.6 + 64 + 3.86

Now all you have to do is add all that together and you have your answer:

23.6 + 64 + 3.86

= 91.46

The complete question is added as an attachment.

The sine function is given as:

y = sin(bx)

And the value of b is given as:

b = 2π/T

Where T = 0.828

Substitute T = 0.828 in b = 2π/T

b = 2π/0.828

Evaluate

b = 7.59

Substitute b = 7.59 in y = sin(bx)

y = sin(7.59x)
